Abstract
An optical film includes a high refractive index pattern layer including a material having a refractive index greater than about 1, wherein a groove pattern defined by grooves, each of which has a curved groove surface and a depth greater than a width, is defined on a first surface of the high refractive index pattern, the grooves are two-dimensionally arranged in a first direction and a second direction, and a cross-sectional shape of each of the grooves has an anisotropic shape, in which a length in a first axial direction and a length in a second axial direction, which is perpendicular to the first axial direction, are different from each other, and a low refractive index pattern layer including a material having a refractive less than the refractive index of the high refractive index pattern layer and further including fillers corresponding to the grooves.
